2 Claims. (CL 261-423) This invention relates to a gas cleaning or suitable design, ,having theoutlet H thereof scwashing device and pertains particularly to a cured to a downwardly extending pipe 2- which device of this character designed primariiy for passes through the top 5 of the casing and a use in association with furnaces or similar strucsubstantial distance downwardly in the casing.

Disposed horizontally within the casing l is a Mounted upon the top 5 is a blower !0 of plate 29 through which the pipes I2 and 24 pass. 55

These pipes are secured to this plate and support the same in the casing. The plate 29 is provided with the integral downturned fiange 30 which is in spaced relation with the walls 3 of the casing so as to provide the passageways 3l. Secured to and extending through the plate 29 is a series of short gas tubes 32 which project above and below the plate, as illustrated. However, the lower ends of these tubes 32 do not extend down to the horizontal plane of the edge of the fiange 36, and this applies also to the lower end of the pipe !2 which extends only a distance as required for a rolled" connection. The pipe 24, however, ex tends downwardly in the casing a substantial distance below the edge of the fiange 353, as illustrated.

When the present device is in service, the casing l is filled with a suitable alkaline solution to a level well above the top ends of the gas tubes 32, and the gauge 9 will be so disposed as to indicate the level of this liquid. With the soot receptacle 28 in position and the fiue pipe 23 connected with a suitable chimney outlet the smoke conduit is connected with the furnace outlet and the smoke from the furnace will be drawn thru the Conduit and driven by the fan H), downwardly through the pipe l2 to discharge into the liquid in the casing, below the tube plate 29. Any heavy soot particles passing through the conduit will drop into the soot receptacle 20 and the lighter soot particles will be driven into the neutralizing fluid in the casing where they Will sink to the bottom and where also the acid forming substances in the furnace gases will be neutralized. The gases and air driven by the fan n below the plate 29 and its fiange 30 forms until a sufficient quantity has collected to force the liquid down so that the gases will escape through the tubes 32. They will then, of course, pass upwardly thru the liquid in the tubes causing an "air lifti' action on the fluid in the tubes causing upward circulation of liquid and pass outwardly through the fiue pipes 23. The annular passageway 3! provides a path for the downward return of liquid to the lower side of dished plate. The escaping gases will naturally carry a considerable amount of moisture as they pass through the pipe 23, and a great deal of this will be condensed bybringing the gas into contact with the baflle plate 28 and With the bafile collars 25, and this condensate will fiow back through the pipe 24 into the lower part of the receptacle.

From the oregoing it will be readily ap parent,

that a device of the character herein described when attached to the gas outlet of a furnace, will operate efciently to remove soot and like ash particles from the furnace gases, and will also neutralize the acid forming fumes commonly found in such gases so that the final gas which is discharged into the atmosphere will have a neutral reaction and will be clean.

What is claimed, is':

1. A furnace attachment of the character described, comprising a closed receptacle, a furnace gas conducting conduit leading downwardly into the receptacle to a point adjacent the bottom thereof, the inlet end of the Conduit being designed for attachment to a furnace gas outlet, a fiue pipe outlet leading from the top of the receptacle, a 'plate disposed horizontally within the receptacle and having the outlet end of said gas Conduit secured thereto and opening to the underside of said plate, a plurality of vertically disposed short gas tubes passing through and extending above and below said partitioning plate, the lower ends of said tubes extending below the outlet end of said gas conduit, a flange extending downwardly from and completely encircling the edge of said partitioning plate and having spaced relation with the sides of the enclosing receptacle, said fiange having its lower edge in a plane below the lower ends of said tubes, and a neutralizing liquid filling the receptacle to a level above the plane of the upper ends of said gas tubes.

2. A gas Washer of the character described, comprising a receptacle having a removable top, a gas inlet pipe secured to and extending through said top and having the inner discharge end thereof terminating in the lower part of the receptacle a Washed gas outlet pipe carried by and opening through said top, a plate member disposed horzontally within the lower part of the receptacle and having a relatively wide downwardly extending surrounding ange, said flange being in spaced relation throughout With the walls of the receptacle and said plate having an opening therethrough in which the lower end of the gas inlet pipe is secured, said gas inlet pipe constituting a supporting means for the plate at one side thereof, supporting means connecting the plate' at the opposite side from the inlet pipe with said top, a plurality of short tubes extending through said plate and having their upper ends extended above the top surface of the plate and their lower ends extended downwardly below the loWer surfa'ce of the plate but terminating short of the plane of the lower edge of said flange, said receptacle being designed to be filled with a neutralizng solution to a level above the upper ends of said tubes, and said discharge end of said gas inlet pipe being above the plane of the lower ends of said tubes whereby gas discharged beneath the plate from said inlet pipe will collect in a body across the underside of the plate.
